The science behind our fertiliser

Our iGrow Carpet Autumn Lawn Builder has a partial coating that pauses nutrient release as soil cools, unlike cheaper fertiliser that unload everything at once, so your lawn avoids late-season growth spurts that can invite disease.

Nitrogen (12% N) Encourages fresh growth and helps your grass grow thicker. It’s what gives your lawn that lush, green look and helps repair damage from the summer.

Phosphate (4% P) Supports strong root growth, making your grass better at finding water and nutrients. This is key for recovery after wear and tear, and sets up a healthy foundation for the months ahead.

Potassium (12% K) Strengthens your lawn and helps it handle stress, such as colder nights and foot traffic. It also helps keep disease at bay, so your grass stays healthy.

Magnesium (4% MgO) is central to chlorophyll production,  this helps your lawn achieve a darker richer shade of green. (Without any staining that comes with cheaper economy products that contain Iron)

Calcium (2% CaO) Improves root strength and overall lawn health. Calcium also helps the soil structure, making it easier for your grass to grow deep, strong roots.
